The operating model is project-based, fee-and-main-contract, with quotes provided per project rather than published pricing. Technology delivery is built on standard BIM/CAD platforms (Revit, BIM 360, AutoCAD, MicroStation, SketchUp) with in-house specialist surveying capability including GPR, thermal imaging, air leakage, and IAQ surveys. The firm reports an 85% client return rate as its principal commercial KPI and is led as an independent private limited company (Cox Design and Consult Ltd) with no disclosed parent, investor, or acquisition activity.
